part ofdevelops_fromcontributes to morphology ofethmoid boneA bone in the skull that separates the nasal cavity from the brain. As such, it is located at the roof of the nose, between the two orbits. The cubical bone is lightweight due to a spongy construction. The ethmoid bone is one of the bones that makes up the orbit of the eye[WP]A light spongy bone located between the eye sockets, forming part of the walls and septum of the superior nasal cavity, and containing perforations for the passage of olfactory nerve fibers.

FMA also has it in neurocranium (via basicranium). Ideally we would have non-overlapping divisions of the skull, but for now we follow FMAOpenCyc:Mx4rvuUPh5wpEbGdrcN5Y29ycAThe ethmoid region of the chondrocranium and the nasal capsules, which were largely unossified in early tetrapods and ancestral amniotes, are represented in mammals by the ethmoid and turbinates bones, respectively.[well established][VHOG]UBERON:0001679UMLS:C0015027VHOG:0001317ethmoidethmoidalethmoidal boneos ethmoidaletodo - homology e.g. mesethmoid of teleostuberonendochondral bonebasicraniumfacial boneethmoid bone primordiumfacial skeletonneurocranium boneethmoid region
